Question

What is the simpler form of (5x^3 + 2)(5x^3 – 2)? (1 point)
25x^6 + 20x^3 – 4
25x^6 – 20x^3 – 4
25x^9 – 4
25x^6 – 4

Answer 1

what is 5*5

What is 2(5*2)

what is 2*2

Answer 2

If you manage to look beyond the numbers, you will see this has the form (a+b)(a-b).
You can write that as \(a^2-b^2\).

The same can be done with \(5x^3\) and 2.

Answer 3

So take the square of \(5x^3\) and subtract \(2^2\)...
